WASHINGTON -LRB- CNN -RRB- -- Iranian-Americans demonstrated on the streets of Washington on Wednesday evening , marching from Iranian diplomatic offices to the Russian embassy , in protest of both governments ' actions .

A Tuesday meeting of Mahmoud Ahmadinejad , left , and Dmitry Medvedev has angered Iranian-Americans .

The demonstration came in the wake of Russian President Dmitry Medvedev hosting Iranian President Mahmoud Ahmadinejad in Moscow on Tuesday , despite allegations of ballot fraud in Ahmadinejad 's re-election last week .

`` We 're hoping that the world attention does not end from what the Iranians are doing right now , because this is not going to end in the next few days , because this is a long haul , a long battle , '' said Washington protest and group organizer Morteza Ahmady . `` Iranians are very capable of deciding their own destiny . ''

The group Whereismyvote.org organized the demonstration of about 100 people and aims to build support for its `` global protest '' this Saturday .

`` I think it 's a very new thing from a historical point of view ; it 's a civic movement . People try to keep it as nonviolent and civil as possible , '' said group organizer Negar Mortarzavi .

In Russia , Ahmadinejad was welcomed as the `` newly re-elected president of Iran , '' with Deputy Foreign Minister Sergei Ryabkov telling reporters , `` the issue of elections in Iran is an internal affair of the Iranian people . ''

Eighty-five percent of the country 's 46 million eligible voters went to the polls on Friday , an unprecedented turnout , Iran 's interior ministry said . When the ballots were counted , the government declared Ahmadinejad the winner , with 62.63 percent of the vote . The man many analysts had widely expected to win , Mir Hossein Moussavi , received 33.75 percent .

The speed with which the election results were released -- two hours after polls closed -- insulted the Iranian people , said Ahmady , who cited that as a sign of fraud .

Moussavi 's camp has demanded new elections .

Sarah , a Washington protester who would give only her first name , agreed .

`` We 're not saying that pro-Ahmadinejad supporters do n't exist ; they do exist , '' she said . `` And we 're saying that , yes , if they indeed did win the vote , then the election should be theirs , because we are a democratic people . But we do n't feel comfortable with the numbers that came out of Iran . And we 're not saying that we do n't accept it altogether . We 're just asking for a revote . ''
